She was wearing a gown. I was very close to her legs and I noticed in the dark that her gown is above her knees. My lund started getting hard. Then I ...ently put my hand on her feet. Let me tell you that she always takes bath before sleep. I start to massage her calf very gently so that she does not wake up. I just wanted to caresses her. Then all of the sudden she pulled her legs and bend her knee upwards. By doing this her gown slipped further above her knees and now I can see her white panty.. .. kiss me to let me know how honist you are." No one will know from me." then I leaned toward her placing my hands on each of mom's shoulders with a slite pull toward me and I kissed her on the mouth, as I would a lover, then I slid my right arm around her pulling her toward me as I slipped my tougne between mom's lips.Mom slid her left arm around me and her right hand went to my hard cock with a jerk of her hand, back off from my cock for a second, then as my tougne slipped into her mouth,. About three minutes after the last employee left the building the doctor came out from the back and called me in to the exam room. The doctor told me to get undressed and to put this paper robe on with the opening to the back. The doctor then left the room and returned when I opened the door. The doctor came back into the room and asked me the usual questions that have been asked for decades. The doctor then asked me if I had, had any problems with getting or maintaining an erection? I told the. That panty was so sweaty. So i used to lick and smell it and rub my cock with it thinking about her. So I did this frequently. And one day my aunt saw me taking her panty and I dint know. But she dint see what I did after that.And one day she peeped into my bedroom and saw me masturbating with her panty and she was shocked. And then I was smelling and licking and she got aroused and she slowly became happy seeing me licking and smelling her dirty panty. Ahhh it was soo good her panty makes me.
